Chipotle will test nachos in Denver and Minneapolis-St. Paul in October, according to its August news release. And there are experiments with 11 p.m. closing times and evening drink discounts Miami and Dallas. Stores in Philadelphia and Indianapolis are testing chip and drink combos.

The menu tinkering is part of a shakeup that began last winter when Brian Niccol became chief executive officer. In May, the company announced it would relocate from its hometown in Denver to Orange County, where Niccol had served as Taco Bell’s CEO.

In July, Niccol told investors the company would be making several changes to remain “culturally relevant,” boosting digital sales and home delivery as well as expanding its menu without disrupting its “make line.”

Chipotle’s reputation as being in the forefront of fast casual dining took a beating in a 2015 e coli outbreak.

The company has moved into temporary digs across from Newport Beach’s Fashion Island.
